I HAVE AN RC10GT AND I HAVE THE ENGINE TUNED UP PRETTY GOOD AND JUST GOT DONE REBUILDING MY DIFF, AND WHEN I HIT THE GAS THE CAR DOESNT GO MUCH

sorry about the caps lol

anyway, i can turn the spur wuth my hand without it turning the tranny, but it is hard to do. What is my problem???
What is supposed to hold the inner and outer cluth hubs together??? just friction and the pad???

**** iwanted to race tomorrow and have no idea what is wrong!!

My first thought is that the diff is in backwards.
The set screw should be behind the right rear dogbone/cvd.

like mentioned above^^, or your clutch is worn out, or maybe even your clutch bell, so before going back into the tranny, check your clutch, its much easier then taking the tranny apart

If the slipper is properly assembled and adjusted, it should be VERY hard to turn without turning the tranny.(nearly impossible if tranny isn't mounted)
